CHIN-REST FOR VIOLINS SPECIFICATION forming part of Letters Patent N0. 651,436, dated June 12, 1900. Application filed November 21, 1899. Serial No. 787,968. (No model.)

To all whom, it may concern/.-

Be it known that I, LEANDER D. OoFFRoN, a citizen of the United States, residing at Grand Rapids,in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Chin-Rests for Violins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

My invention relates to improvements in chin-rests for violins; and its object is to provide a rest that may readily be attached or detached at pleasure and that will fit accurately various sizes of instruments and to provide the same with improved means for attaching to a violin a rest for the mandible or lower jaw and a rest to engage the clavicle or collar-bone, as hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which Figure 1 is a perspective of a device embodying my invention, and Fig. 2 an enlarged vertical section of the same.

Like letters refer to like parts in both of the figures.

A represents a block of wood or othersuitable material having its upper surface concave and the axis of the concavity arranged diagonally across the block, as shown, and adapted to engage the under side of the lower jaw of the player when the block is attached to a violin. B is a smaller block concave on its under side and adapted to engage the collar-bone of the player when the block is attached to the under side of a violin and havin g the axis of its concavity arranged in proper relation to the axis of the concavity of the upper block and diagonal thereto, as shown.

C is a plate of metal attached to the under side of the block A and thence extended downward a proper distance to reach across or nearly across the edge of a violin and provided with rearward-turned lugs D at each side and near the middle thereof, between which lugs is a lever J,'having a divided lower end pivoted to said lugs and between the divided portions of which extends apivotpin J, located above the pivots of the lever, which pin is engaged by a hook I on the upper end of a strap G, provided with a pin II at its lower end to engage a series of openings F in a longitudinally-movable bar F, slidably engaging the plate 0 and held in line therewith by engagement with the lugs D and the lugs E on the lower end of the plate 0, which latter lugs are turned rearward and inward, forming ways in which the bar F is longitudinally movable. The lower end of the bar F and the upper end of the plate 0 are turned at right angles and parallel to each other to embrace the respective upper and lower sides of .a violin, and these opposing faces are provided with pads K, of cork or rubber or other flexible material, to prevent marring the violin or interfering with the sound thereof and also to yield slightly, thus conforming to any slight variance in adj ust ment of the clamping device.

From the foregoing description the opera tion of my device will be readily understood. The pin H, when properly adjusted in one of the holes F, will adapt. the device to the proper thickness of the violin to which it is to be applied. By turning the lever J down the bar F slides downward sufficient to permit the device to be readily placed upon the violin, and by turning the lever up to the position shown the bar F is forcibly drawn upward and the clamping mechanism securely fastened to .the violin. The relative angles of the respective concavities of the blocks A and B adapt them to fit upon the clavicle or collar-bone and beneath the mandible or lower jaw of the operator, and thus afford effective means of holding the violin in place while playing without undue effort on the part of the player.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination of a block adapted to engage the lower jaw, a block adapted to engage the collar-bone, a plate attached to one of said blocks, a bar having a series of openings and attached to the other of said blocks and slidable upon the plate, a lever pivotally attached to the plate, a strap pivoted to the lever and a pin on the strap adapted to engage the openings in the bar, substantially as described.

2. The combination of a block adapted to engage the lower jaw, a plate attached to the block and having lugs at its respective sides and forming ways, a bar slidable in said ways, and having a series of openings, a block adapted to engage the collar-bone and attached to the bar, a lever pivoted to the plate, a strap pivoted to the lever, and a pin on the strap adapted to engage the openings in the bar, substantially as described.

3. The combination of a plate having a forwardly-turned upper end and rearwardlyturned lugs near the middle, and inwardlytnrncd lugs at the lower end forming Ways, a block adapted to engage the lower jaw and attached to the upper end of the plate, a bar slidable on the plate and having a series of
